Neat game! I booted it up and was immediately impressed with the how the game looked! The camera was very smooth and nice and the low poly pop art style was cool, though it does seem to be a more common style now-a-days. I played through all 4 levels, and i felt a thing called enjoyment!
I think if you were to continue developing the game you should focus on the puzzle and physics aspects of the levels. As it stands it's really easy to tell what you have to do and also really easy to execute. Maybe a bigger level would also be cool. What if the level were a cube and you could rotate to all 6 sides??? That would be interesting! Anyway, solid game, and you will probably score pretty high according to these criterion :)
